<p>Device (1) for mechanically testing a pinion (20) that is to be tested, the device comprising: - an annulus (30) provided with internal teeth (31) and configured to mesh with a pinion (20) that is to be tested, the axis (32) of the annulus (30) being fixed with respect to that (22) of the pinion (20) that is to be tested, - an annulus support (33) on which the annulus (30) is placed, - a central movement-transmission element (40) configured to have a rotational movement about an axis (42) that is fixed with respect to that of the annulus (30) provided with internal teeth (31), - a pinion (50) for driving the annulus (30) and which is configured to mesh with the internal teeth (31) of the annulus (30), - a mobile support (60) bearing the pinion (50) that drives the annulus (30), - a support (23) for the pinion (20) that is to be tested and which is fixed with respect to the support (33) for the annulus (30), - means (70) for setting the mobile support (60) in rotation about the axis (32) of the annulus (30) while the assembly (2) formed of the pinion (20) that is to be tested, of the annulus (30) provided with internal teeth (31), of the central transmission element (40) and of the pinion (50) that drives the annulus (30) is set in motion.</p> |
